The museum and cultural development through new technologies is an innovative and constantly evolving issue. Starting from a theoretical framework on the "Economics of Culture and Communication", this volume pays particular attention to investments and projects, particularly in the last decade, that the European Union and the Ministry of Heritage and Culture Italian has been making for the enhancement of culture and museums. With a widely-ranging interdisciplinary this research focuses on the aspects of economy, marketing, communications and new technologies for museums. There are analyzed numerous examples of museums, museum websites, virtual museums and many "excellent" technologies produced in Italy (expecially within the virtual archaeological museums), then, specifically, are described all the technologies used in the field of cultural heritage (from the multitouch screen to mobile devices, including devices relating to the application of augmented reality, used in many examples of virtual archaeology). Finally the volume analyzes the great potential provided by museum web sites and by social networks, with the latest trends of communication, as social-tagging or geo-social tagging.
